Pokemon GO's Supereffective Week gives you a shot at Shiny Tentacool

November's Community Day is behind us but Niantic is bent on making the rest of the month busy for Pokemon GO trainers. This time, it's the Supereffective Week event- it starts today and lets you catch a Shiny Tentacool, if you're lucky.

According to Niantic's announcement, the exact timing is Tuesday, 19 November 2019, at 1pm PST to Tuesday, 26 November 2019, at 1pm PST (GMT −8), so there'll be ample time to try your luck.

"Did you know that Fairy-type moves are super effective in battle against Fighting-type Pokémon? Or that Psychic-type Pokémon are weak to Bug-type moves? Take part in Supereffective Week to learn more about Pokémon types, and you might discover an exciting Pokémon to partner up with in battle against Team GO Rocket", they wrote.

Basically, the Pokemon that might be good partners when taking on Team GO Rocket or other Trainers will be appearing more often, and that goes for the wild, raids and Field Research.

To make the event sweeter, Niantic threw in double the Stardust from Trainer battles, more Potions and Revives from Pokestops and guaranteed charged TM from three-star raids.

Once the Supereffective Week is done, the dev announced that Rock and Fighting-type Legendary Pokemon Terrakion will be heading into five-star raids, so it's quite a November Niantic's got here.

"This Rock- and Fighting-type Legendary Pokémon is said to be strong enough to destroy an entire castle! It'll be in your favor to challenge it with Water-, Grass-, Fighting-, Ground-, Psychic-, Steel-, and Fairy-type Pokemon", they wrote.

Terrakion will be in five-star Pokemon GO raids until Tuesday, 17 December 2019 and will run in parallel with Niantic's Friend Fest, which will be focused on family-themed Pokemon like Nidoran, their evolutions, etc.
